Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

RNA interference in crop protection: opportunities and challenges during the transition to commercialization

Pest Management Science, Volume 82, Issue 7, Page 5971-5986, July 2026.
RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

Interference of small compounds and Mg2+ with dsRNA-binding fluorophores compromises the identification of SARS-CoV-2 RdRp inhibitors

Scientific Reports
The COVID-19 pandemic highlighted the need for the rapid development of antiviral therapies. Viral RNA-dependent RNA polymerases (RdRp) are promising targets, and numerous virtual screenings for potential inhibitors were conducted without validation of ...

Molecular Evolutionary Analyses of the RNA-Dependent RNA Polymerase Region in Norovirus Genogroup II

Frontiers in Microbiology, 2018
Noroviruses are the leading cause of viral gastroenteritis in humans across the world. RNA-dependent RNA polymerase (RdRp) plays a critical role in the replication of the viral genome.

Potato leafroll virus: A re‐emerging threat to sustainable potato production

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Potato leafroll virus (PLRV) is a positive‐strand RNA virus. Virus particles of PLRV are isometric, 24 nm in diameter. PLRV is the causal agent of leafroll disease in potato (Solanum tuberosum L.) which causes significant losses in yield and quality of potato tubers.

Structural Dynamics of Picornaviral RdRP Complexes. Implications for the Design of Antivirals

, 2011
Genome replication in picornavirus is catalyzed by a virally encoded RNA dependent RNA polymerase, termed 3D. These viruses also use a small protein primer, named VPg to initiate RNA replication. Polymerase 3D also catalyzes the covalent linkage of UMP to a N-terminal tyrosine on VPg.

NeoRdRp2 with improved seed data, annotations, and scoring

Frontiers in Virology
RNA-dependent RNA polymerase (RdRp) is a marker gene for RNA viruses; thus, it is widely used to identify RNA viruses from metatranscriptome data. However, because of the high diversity of RdRp domains, it remains difficult to identify RNA viruses using ...

Synthesis and Evaluation of Aromatic Sulfonamide and Disulfonamide Derivatives as Dengue Virus NS3–NS5 Interaction Inhibitors

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
A synthetic methodology for the preparation of asymmetric benzene‐1,4‐disulfonamides was developed and applied to generate potential anti‐dengue virus (DENV) compounds. Guided by computer‐assisted structural rationalization, we designed synthetically more accessible analogs with reduced toxicity that interact with the DENV NS5 domain, thereby ...

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

Systemic Expression of a Viral RdRP Protects against Retrovirus Infection and Disease

Journal of Virology, 2020
Immune control of retroviruses is notoriously difficult, a fundamental problem that has been most clinically consequential with the HIV-1 pandemic. As humans expand further into previously uninhabited areas, the likelihood of new zoonotic retroviral exposures increases.
